... There were too many English-speaking natives (and not a few spies) in our camp to make it safe to utter a word as to our future movements.  Amongst the latter was Kobina Foli, the heir to the Adansi stool, who had voluntarily given himself up when Inkanza, the King, raised the flag of rebellion; and although I must own he had given no specific cause for suspicion, yet he was too acute a man to be thoroughly trusted, and, I believed, was trying to play a double game.
